SAW SET AND GAGE.

SPECIFICATION forming part of Letters Patent No. 482,250, datedSeptember 6, 1892.

Application filed May 29, 1891. Serial No. 394,542. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES F. HEATH, a citizen of the United States,residing at Durham, Butte county, State of California, have invented anImprovement in Saw Sets and Gages; and I hereby declare the following tobe a full, clear, and exact description of the same.

My invention relates to a device which is especially applicable to thesetting of the teeth of crosscut-saws and gaging the set thereof, thiswork being accomplished without recourse to a shop or large set oftools. a

It consists of a block of metal having one end formed to serve as ananvil, upon which the points of the teeth may be set, the anvil beingheld in one hand and the hammer by which the points are bent or setbeing held in the other. This block has formed upon another edge of itdevices by which the gaging of the set is effected, and upon stillanother edge a means for effecting a set by what is known as aspring-set.

Referring to the accompanying drawings for a more complete explanationof myinvention, Figure 1 is a view showing a portion of a saw and thedevice in position for setting a tooth. Fig. 2 shows it in position forgaging the set of a tooth. Fig. 3 shows it in the form of a wrench forsetting the tooth. Fig. 4 is a perspective view of the gage.

This device is a hand-tool especially designed for the use of sawyers atwork in the woods at a considerable distance from any point Where toolscan be obtained for keeping saws in order. It consists of a block A,having at one end the anvil, which has a surface bent or curved slightlyfrom a right angle, as shown at B. The opposite end of the block istapered or beveled off, so that it may be conveniently held in the hand,and the anvil being held against a tooth of the saw the latter is struckfrom the opposite side with a hammer until the point is bentor set asmuch as may be desired.

For the purpose of holding a crosscut-saw sufficiently to beconveniently reached. The tooth being set by striking its point upon theanvil, the gage is then dropped down, as shown in Fig. 2, and the set ofthe tooth is deter mined by means of the projecting lug C, the legs D,which project from the same edge of the block about midway between theprojection 0 and the opposite end of the block, and a screw E, whichpasses through the rear end of the block. This screw is set to the pointwhich will allow the legs D D and the point of the screw to rest uponthe side of the sawblade, while the projection 0 should just touch thepoint of the tooth when the set is sufficient. If the set is notsufficient, it will be manifest that the gage will rest upon the pointof the screw and the two legs D, while the projection C will not touchthe point of the screw; but if the set is too great the projection willtouch the point of the tooth and a screw will rest upon the saw-blade,while the legs D not having any contact with the blade to steady it, thedevice will rock from side to side about the points of support at C andE. If this should be the case, the tooth must be set back a little,while if the set is not suificient the tooth is easily bent or set tothe proper position. The tooth may be set back if the set is too great,either by using the end anvil, as previously described, or by turningthe block so that the tooth rests upon the top, which is a planesurface, and striking it with a hammer. In this manner all the teeth ofthe saw maybe rapidly set and gaged with the single tool.

F is aslit made transversely across the edge of the tool opposite to thegage, and when it is desired to set the tooth by bending it to one sideWithout using the hammer the point of the tooth is simply inserted intothis cut and pressure brought upon the opposite end, using the tool as alever to bend the point of the tooth to one side. The gaging of the setWill be done in the same manner as previously described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A saw set and gage consisting of the block of metal having the inclinedface at one end serving as an anvil upon which the saw-tooth Ice is set,the projection or lug 0, extending crosswise the block at one end, theindependent separated legs D at the sides of the block and outside ofthe plane of its walls, and the adjustable screw E, passing through theblock, so that its point, the endsof the lug, and the two legs D will bein contact with the side of the saw-blade and the point of the toothwhen the latter is properly set, substantially as herein described. IO

In witness whereof I have hereunto set my hand.
